| Military-Grade 10BASE-T interface module Fully integrated 10BASE-T module for adapter, hub, and motherboard applications. s Designed to meet IEEE802.3i-1993 10BASE-T specifications. s Low profile surface mount package s 235C peak infrared reflow temperature rating s Operating temperature -40C to +85C. s Parts can be screened to MIL-T-21038 and other military specific requirements s CHARACTERISTICS Part Number Insertion Loss 1-10 MHz (dB max) 30 MHz 10B-2001 -10 -30 50 MHz -35 100 MHz -35 100 ohms -18 98 13 ohms Attenuation XMIT (dB min) Return Loss 5 to 10 MHz (dB min) Crosstalk (dB min) Common Mode Rejection (dB min) Pri-Sec Isolation (Vrms min) 5-10 MHz -35 5-10 MHz -60 50 MHz -55 100 MHz -50 200 MHz -45 -15 1500 1) Receive and transmit sides meet IEEE 802.3i-1993 specification, transmit side is enhanced for FCC/VDE class B system emissions requirement. Specifications reflect filter sections, additional attenuation is due to pre-distortion resistors. MECHANICAL OUTLINES TEC H N I R O L T Notes: 1. Weight = 2.5 grams. 2.

TWO PEARL BUCK COURT q BRISTOL, PA 19007-6812 q TEL 215-781-6400 q FAX 215-781-6403 q www.pulsespecialty.com APPLICATION NOTES The module contains low pass filters, isolation transformers, and common mode chokes. These components provide impedance matching, equipment isolation, and EMI compression to comply with IEEE requirements. User compliance with FCC/ CSPR class B requirements can be achieved by applying rigorous design guidelines to suppress noise mechanisms. Attention to high frequency signal paths, proper PCB grounding techniques, and component placement is critical. Pins 5 and 12, when grounded, provide noise return paths. At least one of these (typically pin 12) must be coupled with bypass capacitor. Recommended module orientation with respect to RJ45 connector is illustrated in the application circuit. Output pins 6 through 11 should be routed with short, matched traces to the connector for optimum EMI performance. The robust mechanical package withstands IR reflow temperatures up to 235C. Compliant leads provide excellent solder-joint reliability with K.002 coplanarity. Modules are shipped in tubes.
